## Releases ## Usage
**Important:** all the 2.x releases are deployed to npm and can be used with Redocly-cdn:
- particular release, for example, `v2.0.0`: https://cdn.redoc.ly/redoc/v2.0.0/bundles/redoc.standalone.js
- `latest` release: https://cdn.redoc.ly/redoc/latest/bundles/redoc.standalone.js
Additionally, all the 1.x releases are hosted on our GitHub Pages-based CDN **(deprecated)**: Redoc is provided as a CLI tool (also distributed as a Docker image), HTML tag, and React component.
- particular release, for example `v1.2.0`: https://rebilly.github.io/ReDoc/releases/v1.2.0/redoc.min.js
- `v1.x.x` release: https://rebilly.github.io/ReDoc/releases/v1.x.x/redoc.min.js
- `latest` release: https://rebilly.github.io/ReDoc/releases/latest/redoc.min.js - points to latest 1.x.x release since 2.x releases are not hosted on this CDN but on unpkg.
## Version Guidance ### Generate documentation from the CLI
| Redoc Release | OpenAPI Specification |
|:--------------|:----------------------| If you have Node installed, quickly generate documentation using `npx`:
| 2.0.0-alpha.54| 3.1, 3.0.x, 2.0 |
| 2.0.0-alpha.x | 3.0, 2.0 | ```
| 1.19.x | 2.0 | npx @redocly/cli build-docs openapi.yaml
| 1.18.x | 2.0 | ```
| 1.17.x | 2.0 |
The tool outputs by default to a file named `redoc-static.html` that you can open in your browser.
> [Redocly CLI](https://github.com/Redocly/redocly-cli/) does more than docs, check it out and add linting, bundling and more to your API workflow.
### Add an HTML element to the page
Create an HTML page, or edit an existing one, and add the following:
```html
<redoc spec-url="http://petstore.swagger.io/v2/swagger.json"></redoc>
<script src="https://cdn.redoc.ly/redoc/latest/bundles/redoc.standalone.js"> </script>
```
Open the HTML file in your browser, and your API documentation is shown on the page.
Add your own `spec-url` to the `<redoc>` tag, this attribute can also be a local file. The JavaScript library can also be installed locally using `npm` and served from your own server, see the [HTML deployment documentation](https://redocly.com/docs/redoc/deployment/html/) for more details.
### More usage options
Check out the [deployment documentation](./deploment/index/md) for more options, and detailed documentation for each.

## Lint OpenAPI definitions _Pull requests to add your own API page to the list are welcome_
Redocly CLI is an [open source command-line tool](https://github.com/Redocly/redocly-cli) that you can use to lint
your OpenAPI definition. Linting helps you to catch errors and inconsistencies in your
OpenAPI definition before publishing.
Learn more about [API standards and linting](https://redocly.com/docs/cli/api-standards/) in the main Redocly documentation.
## Deployment
### TL;DR final code example
To render your OpenAPI definition using Redoc, use the following HTML code sample and
replace the `spec-url` attribute with the url or local file address to your definition.
```html
<!DOCTYPE html>
<html>
<head>
<title>Redoc</title>
<!-- needed for adaptive design -->
<meta charset="utf-8"/>
<meta name="viewport" content="width=device-width, initial-scale=1">
<link href="https://fonts.googleapis.com/css?family=Montserrat:300,400,700|Roboto:300,400,700" rel="stylesheet">
<!--
Redoc doesn't change outer page styles
-->
<style>
body {
margin: 0;
padding: 0;
}
</style>
</head>
<body>
<redoc spec-url='http://petstore.swagger.io/v2/swagger.json'></redoc>
<script src="https://cdn.redoc.ly/redoc/latest/bundles/redoc.standalone.js"> </script>
</body>
</html>
```
For step-by-step instructions for how to get started using Redoc
to render your OpenAPI definition, refer to the
[**Redoc quickstart guide**](https://redocly.com/docs/redoc/quickstart/) and [**How to use the HTML element**](https://redocly.com/docs/redoc/deployment/html/).
## Configuration ## Configuration
### Security Definition location Redoc is highly configurable, see the [configuration documentation](docs/config.md) for details.
You can inject the Security Definitions widget into any place in your definition `description`.
For more information, refer to [Security definitions injection](docs/security-definitions-injection.md).

### `<redoc>` options object
You can use all of the following options with the standalone version of the <redoc> tag by kebab-casing them. For example, `scrollYOffset` becomes `scroll-y-offset`, and `expandResponses` becomes `expand-responses`.
* `disableSearch` - disable search indexing and search box.
* `minCharacterLengthToInitSearch` - set minimal characters length to init search, default `3`, minimal `1`.
* `expandDefaultServerVariables` - enable expanding default server variables, default `false`.
* `expandResponses` - specify which responses to expand by default by response codes. Values should be passed as comma-separated list without spaces e.g. `expandResponses="200,201"`. Special value `"all"` expands all responses by default. Be careful: this option can slow-down documentation rendering time.
* `generatedPayloadSamplesMaxDepth` - set the maximum render depth for JSON payload samples (responses and request body). The default value is `10`.
* `maxDisplayedEnumValues` - display only specified number of enum values. hide rest values under spoiler.
* `hideDownloadButton` - do not show "Download" spec button. **THIS DOESN'T MAKE YOUR SPEC PRIVATE**, it just hides the button.
* `downloadFileName` - set a custom file name for the downloaded API definition file.
* `downloadDefinitionUrl` - If the 'Download' button is visible in the API reference documentation (hideDownloadButton=false), the URL configured here opens when that button is selected. Provide it as an absolute URL with the full URI scheme.
* `hideHostname` - if set, the protocol and hostname is not shown in the operation definition.
* `hideLoading` - do not show loading animation. Useful for small docs.
* `hideFab` - do not show FAB in mobile view. Useful for implementing a custom floating action button.
* `hideSchemaPattern` - if set, the pattern is not shown in the schema.
* `hideSingleRequestSampleTab` - do not show the request sample tab for requests with only one sample.
* `showObjectSchemaExamples` - show object schema example in the properties, default `false`.
* `expandSingleSchemaField` - automatically expand single field in a schema
* `schemaExpansionLevel` - specifies whether to automatically expand schemas. Special value `"all"` expands all levels. The default value is `0`.
* `jsonSampleExpandLevel` - set the default expand level for JSON payload samples (responses and request body). Special value `"all"` expands all levels. The default value is `2`.
* `hideSchemaTitles` - do not display schema `title` next to to the type
* `simpleOneOfTypeLabel` - show only unique oneOf types in the label without titles
* `sortEnumValuesAlphabetically` - set to true, sorts all enum values in all schemas alphabetically
* `sortOperationsAlphabetically` - set to true, sorts operations in the navigation sidebar and in the middle panel alphabetically
* `sortTagsAlphabetically` - set to true, sorts tags in the navigation sidebar and in the middle panel alphabetically
* `menuToggle` - if true, clicking second time on expanded menu item collapses it, default `true`.
* `nativeScrollbars` - use native scrollbar for sidemenu instead of perfect-scroll (scrolling performance optimization for big specs).
* `onlyRequiredInSamples` - shows only required fields in request samples.
* `pathInMiddlePanel` - show path link and HTTP verb in the middle panel instead of the right one.
* `requiredPropsFirst` - show required properties first ordered in the same order as in `required` array.
* `scrollYOffset` - If set, specifies a vertical scroll-offset. This is often useful when there are fixed positioned elements at the top of the page, such as navbars, headers etc;
`scrollYOffset` can be specified in various ways:
* **number**: A fixed number of pixels to be used as offset.
* **selector**: selector of the element to be used for specifying the offset. The distance from the top of the page to the element's bottom is used as offset.
* **function**: A getter function. Must return a number representing the offset (in pixels).
* `showExtensions` - show vendor extensions ("x-" fields). Extensions used by Redoc are ignored. Can be boolean or an array of `string` with names of extensions to display.
* `sortPropsAlphabetically` - sort properties alphabetically.
* `payloadSampleIdx` - if set, payload sample is inserted at this index or last. Indexes start from 0.
* `theme` - Redoc theme. For details check [theme docs](#redoc-theme-object).
* `untrustedSpec` - if set, the spec is considered untrusted and all HTML/markdown is sanitized to prevent XSS. **Disabled by default** for performance reasons. **Enable this option if you work with untrusted user data!**
* `nonce` - if set, the provided value is injected in every injected HTML element in the `nonce` attribute. Useful when using CSP, see https://webpack.js.org/guides/csp/.
* `sideNavStyle` - can be specified in various ways:
* **summary-only**: displays a summary in the sidebar navigation item. (**default**)
* **path-only**: displays a path in the sidebar navigation item.
* **id-only**: displays the operation id with a fallback to the path in the sidebar navigation item.
* `showWebhookVerb` - when set to `true`, shows the HTTP request method for webhooks in operations and in the sidebar.
